SPECIFICATION formingpart of Letters Patent No. 634,079, dated october e, 1899.

Applicationfiled January 26,1899. Serial lloflfl. n (No model.)

Beit known that I, WILLIAM C. WINFIELIS, a citizen ofthe United States,'residin g atWarren, in the countyof Trumbull and State of Ohio,'have invented certain new and useful.l

Improvements in Lift Mechanism for Tubular Lanterns; and I do declare that the fol-VV lowing is'a full, clear, and exact description of the invention', which v"will enable others "skilled in the art to which it appertains to make and use they same. y l

This invention has reference to lift mechj vanisni for tubular lanterns; and the object of the invention is toprovide means for conveniently raising the globeto effect lighting and to lower the globeagain to its seat, all

substantially as described and shown, and

particularlypointed out in the claims.

, In the accompanying drawings, Figure l is a front elevation of my improved lantern,

showing the globe seated. Fig.v 2 is a side elevation with parts broken away and showing the globe raised. Fig.3 is a cross-section nOnline 2 2, Fig. l, lookingupward and in dotted lines showing the lift mechanism in the half-raised position.

.A represents the usual tubes or tubular frame of the lantern, and B is the globe car'- ried by the frame, consisting of the side wires C, bottom plate D, and Vcanopy E. These latter parts are connected to be raised and lowered together, a spring-wire loop b confining the' globe at its top, as usual. k

G is a crank liftingflever shaped substantiallyvas seen in Fig. l and pivoted at about.I .its middle in a suitable bearing aon the side tically ofthe inner entremity of crank-lever G as it makes its curved'sweep transversely baclr'and forth inraising.and lowering the globe, and the sleeve H affords yboth a slid- Y ing. and a pivotal connectionfwith said arm. This makes a very easy operating movement,

asthe sleeve readily accommodates itself to ythe diierent' positions ofy the lifting-lever in its rotations.

L is a Wire spring bent into a loop and secured at oneend to the globe-plate D and at the other to the inner extremity of lever G or to the sleeve H and coperatingwith the lever in raising and lowering the globe, as wellas serving to helpto hold the globe sef curely in both raised and lowered positions.

Thus when the crank-lever lifts the globe `it no sooner reaches the vhorizontal or halfway position than the spring J begins to eX- 4ert an upward or lifting pressure, and it alone will securely hold'the" globe up without other means for locking lever H. On the -other hand, in lowering the globe after the half' way place is passed the spring exerts a downi,

ward pressure, andI as the globe becomes seated it maintains a constant downward pull, thus keeping all the parts in their place.

(",The usual guides ct on the tubes for the side wires `C are employed, and the canopyis free to slide and rise on the centraldraft-tube a', as seen in Fig. 1.

What I claim is" k y1. In a tubularlantern, the globe-carrying frame, an arm rigid with said frame and a sliding member on said arm, the tubes and a.

lever pivoted thereon and loosely connected with the said sliding member, whereby the globe isV raised and lowered, substantiallykas described.

2.` The globeframe andan arm lined on the bottom thereof, in combination withk the tubes and the swinging lever, and a part sleeved on said armand Yfreely connected with said lever, substantially as described.

3. The`tubular' frame and the lifting-lever supported thereon, in combination with the vertically-movable globe-frame, anv arm on the said frame having L straight portion suband a spring operatively connected with said ro stantiziily in the path of said level', and :i :i1-m, substantially :is described.

Sleeve on said straight portion pivotallyeonvWitness my hand to the foregoing 'specifineoted. with the said lever, substantially as cation this 12th day of January, 1899. described.
